101. Sound is sent from the radio station through the air to
your radio by means of electromagnetic waves. News, music, Bible teaching,
baseball games, plays, advertisements- these sounds are all converted into
electromagnetic waves (radio waves) before they reach your radio and your ears.
102. At the radio station, the announcer speaks into a microphone.
The microphone changes the sound of his voice into an electrical signal. This
signal is weak and can't travel very far, so it's sent to a transmitter.
The transmitter mixes the signal with some strong radio signals called carrier
waves. These waves are
then sent out through a special antenna at the speed of
light! They reach the antenna of your radio. Your antenna "catches"
the signal, and the radio's amplifier strengthens the signal and sends it to the
speakers. The speakers vibrate, and your ears pick up the vibrations and your
brain translates them into the voice of the radio announcer back at the station. When
you consider all the places the announcer's voice travels
103. Every radio station has its own frequency. When you
turn the tuning knob on your radio, you are choosing which frequency you want
your antenna to "catch."
